HOLDER FOR ROTARY SPINNING-RINGS.

Specification of Letters Patent. Patented Mar. 22, 1910. Application filed July 22, 1909. Serial No. 508,920.

To all whom it may concern:

Before the The present invention seeks to avoid the members 14 and 15 are assembled, the inconvenience of manipulating the attaching tongues 16 may be bent to a perpendicular screws of a ring holder by arranging the position, as shown in Figs. 7 and 8, and, screws in the rails so that they extend horiafter they have been assembled, the tongues zontally with their heads in the front edges may be bent slightly farther, as shown by thereof, and by forming the ring holders Fig. 2, so as to clench the member 14.

At each spindle hole is a horisake of avoiding, so far as possible, the exontal screw-threaded socket 22 extending pense of manufacture. For this reason, the from the front edge of the rail tothe hole. two parts are preferably composed of sheet As shown 1n Fig. 2, a screw 21, inserted in such a socket is adapted to engage the pe- 119 metal cut and formed by dies and adapted riphery of the cylindrical portion 20 so as to bind the base member in the rail. A single screw 21 is sufficient to bind a ring holder formed with a neck portion 20, whereas two screws are necessary for those ring holders which do not have a similar portion but which bear solely upon the top of the rail.

Freedom of manipulation of the screws is apparent, since neither the spindles nor any other part of a spinning machine may be an obstacle.

Having thus explained the nature of my said invention and described a Way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, what I claim is:

A holder for a rotary spinning ring, comprising two members, to wit; an annular cylindrical neck extending Vertically, and an annular supporting member for a spinning ring, said neck and supporting member having complemental portions adapted to be interengaged to lock them together, and said supporting member having an annular seat for contact with a spinning ring, and upwardly extending tongues for loose engagement with the interior of the ring.

In testimony whereof I have afliXed my signature, in presence of two witnesses.
